Wildlife-related accidents are a serious problem in different countries and describing their temporal pattern allows for the development of measures to mitigate them. We described the temporal pattern of wild ungulate-related accidents occurring between January 2006 and December 2010 in the Autonomous Region of Galicia, northwest of Spain. We exami...
En la presente tesis doctoral se aborda la utilización de diferentes combinaciones de sensores de teledetección para monitorizar y gestionar los bosques en sistemas forestales dominados por minifundismo y continuamente sujetos a perturbaciones (cortas e incendios). En particular: imágenes Sentinel-2, imágenes WorldView-3, ALS (LiDAR aerotransportad...
Climate change-associated disturbances such as storms, wildfires, and pest outbreaks increasingly destabilize forest systems, threatening their ecological, economic, and social functions. These disruptions impact the forest value chain (FVC) by causing fluctuations in timber supply, from a quantity and quality perspective. This study employed the o...

El Mercado Global de Productos de Madera: Innovación y Sostenibilidad
La madera ha sido, a lo largo de toda la historia, el producto más importante derivado de los bosques. Sus mercados, algunos de larguísima tradición, juegan un papel crucial en la economía global. La madera es algo más que una fuente de ingresos para los propietarios forestales...
The paper industry contributes significantly to the transformation of native forests into monocultures of fast growing exotic species such as Eucalyptus globulus, reducing biodiversity. This expansion, driven by the demand for cellulose-based products, threatens ecosystems by displacing native flora and causing soil impoverishment. To address these...
In the current context of extreme wildfires, understanding fire behavior at a territorial level has proven crucial for territory planning. This type of analysis is usually conducted by analyzing past wildfire statistics. In this study, we forego the past information related to wildfires and analyze, instead, the behavior of the entire territory in...
Unlike the conventional resin tapping processes throughout long periods of time or the complete life of the trees, in which the cellular and physical–mechanical characteristics of the whole wood could be modified, the resin tapping system, only in the last years before the ideal-timber cutting shift, shows no significant influence on some physical–...
Forest inventories are essential for sustainable forest management. In inventories at the tree level, all the information is linked to individuals: species, diameter, height, or spatial distribution, for example. Currently, the implementation of Portable LiDAR (PLS) is being studied, aiming to digitalize forest environments and increase the reliabi...
In order to have sustainable wood value chains, it is essential to understand the factors that determine the incorporation of wood resources into them. Forest contractors are among the key players in this process. This study evaluates the preferences of forest contractors when purchasing forest parcels. The variables considered are: slope of the te...
One of the current concerns for Spanish and European pine forests lies in the pinewood nematode Bursaphelenchus xylophilus (PWN), responsible for causing pine wilt disease. This nematode has emerged as one of the most dreadful threats in those countries where it is not native, leading to substantial environmental and economic damages in stands of v...
Paper industry contributes significantly to the transformation of native forests into monocultures of exotic species, such as Eucalyptus globulus. This monoculture expansion not only reduces biodiversity in cultivated areas but also in adjacent regions. Ecological concerns, the demand for cellulose-based products continues to rise, driving an incre...

Eucalyptus constitutes one of the most common tree genera used in forest plantations worldwide. In Europe, Eucalyptus trees are especially common in the Northwest of the Iberian Peninsula, E. nitens and E. globulus being the most commonly cultivated species. Each species presents particularities that lend to different exploitation strategies and in...
The growth of technology in recent decades has ushered in a new era of sustainable forest management. This is due to the significant number of tools that have been created, new methodologies that have emerged, and the wealth of information and data available for incorporation into decision-making processes. This growth has, for example, contributed...
The forest value chain is key to the European transition to a climate-neutral economy. Sustainable forest management is essential for this task. To plan sustainable forest management, it is essential to track forest resources in relation to their feasibility for wood supply. This means considering the constraints that may limit the incorporation of...
Background
In the new era of large, high-intensity wildfire events, new fire prevention and extinction strategies are emerging. Software that simulates fire behavior can play a leading role. In order for these simulators to provide reliable results, updated fuel model maps are required. Previous studies have shown that remote sensing is a useful to...
Throughout history, the use of animals for agricultural and forestry work has been closely associated with human societies, with multiple references to animal power being utilized for various tasks since the Neolithic period. However, the advent of industrialization has fundamentally transformed the reality of society, leading to a significant shif...
Land cover mapping is fundamental for national and international agencies to monitor forest resources. However, monitoring forest disturbances by direct comparison of these maps poses several difficulties and challenges. As a result, different methodologies have been explored to detect forest disturbances. However, most of them cannot be fully inte...
Key message
This study details a methodology to automatically detect the positions of and dasometric information about individual Eucalyptus trees from a point cloud acquired with a portable LiDAR system.
Abstract
Currently, the implementation of portable laser scanners (PLS) in forest inventories is being studied, since they allow for significant...
In numerous countries, official forest cartography is obtained through photointerpretation of aerial images which hinders having up-to-date information. This study explores the usefulness of a land cover map produced automatically using Sentinel-2 images as a complement of the official Spanish forest map in Galicia. It was obtained a map with an Ov...
Background
In the new era of extreme wildfire events, new fire prevention and extinction strategies are emerging using software that simulates fire behavior.

Enquisa elaborada por XERA, Axencia Galega da Industria Forestal - Consellería de Economía, Emprego e Industria, Xunta de Galicia en colaboración coa Escola de Enxeñaria Forestal de Pontevedra (Universidade de Vigo) para poder deseñar medidas sectoriais que permitan mitigar os efectos negativos do COVID19 na industria forestal galega.
The present study addresses the tree counting of a Eucalyptus plantation, the most widely planted hardwood in the world. Unmanned aerial vehicle (UAV) light detection and ranging (LiDAR) was used for the estimation of Eucalyptus trees. LiDAR-based estimation of Eucalyptus is a challenge due to the irregular shape and multiple trunks. To overcome th...
To optimize suppression, restoration, and prevention plans against wildfire, postfire assessment is a key input. Since little research has been carried out on applying Sentinel-2 imagery through an integrated approach to evaluate how environmental parameters affect fire severity, this work aims to fill this gap. A set of large forest fires that occ...
